Explanation:
The Oracle Management Agent on a host collects host configuration information for the host and database configuration information for the Oracle databases on the host and communicates that information over HTTPS to the Oracle Management Service, which stores it in the Oracle Management Repository.You can use Enterprise Manager to see whether targets in your enterprise configuration (such as hosts, databases, and listeners) are following the policies for those target types. The policies include different categories of policy rules, such as configuration, security, and storage rules. The policy rules are given different priorities, including High, Medium, and Informational. Enterprise Manager compares the targets for which policy rules exist with the policy rules for that target type, and identifies the policy violations for the target.You can examine the policy violations for one or more targets and choose to fix or ignore individual violations. For more information about managing violations, see Managing Policy Violations. You can also disable one or more policy rules for a target type. When a policy rule for a target type is disabled, targets of that type are no longer evaluated to see if they comply with the rule.
